This series is based on exynos-drm-next branch of Inki Dae's tree at: git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git
I have tested this after adding few DT changes for exynos5250-snow, exynos5420-peach-pit and exynos5800-peach-pi boards.
I'm trying to test this with a modified exynos5250-spring DT based off kgene's for-next branch due to DT, and I run into the following:
Unfortunately the most I got on Spring with attached DT was a blank screen with a white horizontal line in the middle.
Then, I think bridge chip is working fine. You just need to configure the proper mode for FIMD. You can see backlight also, right?
Do I need to specify a specific panel model for Spring?
Yes! Try using "chunghwa,claa101wb01" as compatible string for panel node.
With just your v6 applied plus updated DT patch (attached) [1], I see backlight and a black screen (no white line any more). dmesg attached.
For testing I re-applied your iommu patches (which btw fail now for 5420 due to disp_pd) but didn't know what to do about your panel-lvds regulator patch now that it's gone.
Ignore that regulator patch.
Also, please attach the bootlog if possible after trying this.
If I further apply the IOMMU patches [2], I get no backlight nor USB and thus can't obtain a boot log.

P.S. Note that your Snow DT patch will conflict with my Snow cleanups, shuffling some nodes around: https://patchwork.kernel.org/patch/4649471/
